Symbiont alpha-diversity - Grouped by Species
First, we look at how many Symbiodinium types (OTUs) and clades are present in each coral species:

Next, we look at the number of Symbiodinium types (OTUs) and clades in coral at each Kiritimati site:

OTU and Clade Diversity by Disturbance Level
Symbiont alpha-diversity - Grouped by Field Season
To understand how Symbiodinium diversity changes among field seasons, clade diversity is divided by field season. This includes coral-associated Symbiodinium.

Principal and Background Types
Background Symbiodinium types are those which have <0.01% abundance, and Principal Symbiodinium types are those which ahve >0.01% abunance (per Quigley et al 2017).
